There are all sorts of things that can be issues in major real estate transactions. One such thing are easements.
An easement is a nonpossessory right regarding a property owned by someone else. Most easements tend to involve the right to use a portion of the land of another. One example of an easement is a property owner being given the right to use a path on a neighboring property to get to and from their property. Much of the time, easements come into being through a written document.
